Connection point changes
Some common examples of actions resulting in a change to the connection point include:
- a meter is removed, or a new one is added.
- a current transformer is being added or removed.
- the status of the revenue meter is changing for example will be converted to a sub-meter or an embedded network is being installed.
- the connection is changing from low to high voltage or vice versa.
If a customer doesn’t know if the connection point will change, Western Power can assess and advise as part of the application process.
The retailer is responsible for each connection point where electricity is supplied to their customer using the Western Power network, so they need to know what's going on.
To approve a customer's request to change the connection point, we need to be advised by the retailer what change its permitting.
If the retailer doesn't get involved, we’re not able to process the customer's application beyond the design stage.
Western Power will place the application on hold for a set period and ask the customer to contact the retailer.
We’ll provide each customer with a unique reference number related to their application. This number allows us to track the project and respond to any enquiries.
The customer should keep this number – it's important and we'll always ask for it. It's also the reference number that will need to be provided to the retailer.
When the retailer provides their approval, they will quote this number so we can match it to the customer's application.
Before construction starts, Western Power agrees the scope with the customer, we understand however that sometimes, plans change. If the scope changes, we need to assess what these changes involve.
If this work modifies the connection point, the retailer will need to get involved.
This information is for applicants proposing changes to an approved High Voltage (HV) connection point.
Any change to an approved HV connection point, including changes driven by new generation equipment, must be identified early. You must discuss the change with the Network Engineering Review (NER) engineer and notify the Network Operator in line with the Wholesale Electricity Market Security and Reliability Rules (WASIR) clause 13.7.2 and the Wholesale Electricity Market Electricity Access Rules (WAER) section 7.
If the HV connection point differs from what was previously assessed or approved, you must submit a revised HV submission. Address this as early as possible. Changes required to remain compliant can take time to resolve and may affect the progress of your connection application. This helps support the safe and reliable operation of the network.
To submit a revised HV connection point, complete the HV Submission – Initial Checklist and email it, with all required supporting documentation, to the address listed on the checklist.
Please note, draft submissions will not be accepted.
Once received, the Customer Operations team will:
- register the HV submission
- issue an HV submission reference number
- assess the submission and provide a response.
This HV submission process is separate from the distributed energy resources (DER) connection application process.
If you have questions, email ccs.customer.finance@westernpower.com.au and include your HV submission reference number.
